How do I find the factor combinations of the number 9,239,857?

Unfortunately, there's not simple formula to identifying all of the factors of a number and it can be a tedious process when trying to identify the divisors of larger numbers. To find the factor combinations of the number 9,239,857, it is easier to work with a table - it's called factoring from the outside in.

Outside in Factoring

We start by creating a table and writing 1 on the left side and then the number we're trying to find the factors for on the right side in a table. Then, below that, write the numbers as a negative as well.

1 9,239,857
-1 -9,239,857

Why are the negative numbers included?

When you multiply two negative numbers together, you get a positive number. That means both the positive and negative numbers are factors of 9,239,857.

Example:
1 x 9,239,857 = 9,239,857
and
-1 x -9,239,857 = 9,239,857
Notice both answers equal 9,239,857

With that explanation out of the way, let's continue. Next, we take the number 9,239,857 and divide it by 2:

9,239,857 ÷ 2 = 4,619,928.5

If the quotient is a whole number, then 2 and 4,619,928.5 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.

Here is what our table should look like at this step:

1 9,239,857
-1 -9,239,857

Now, we try dividing 9,239,857 by 3:

9,239,857 ÷ 3 = 3,079,952.3333

If the quotient is a whole number, then 3 and 3,079,952.3333 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.

Here is what our table should look like at this step:

1 9,239,857
-1 -9,239,857

Let's try dividing by 4:

9,239,857 ÷ 4 = 2,309,964.25

If the quotient is a whole number, then 4 and 2,309,964.25 are factors. In this case, the quotient is not a whole number. Don't write anything down and try the next divisor.

Here is what our table should look like at this step:

1 9,239,857
-1 9,239,857
Keep dividing by the next highest number until you cannot divide anymore.

If you did it right, you will end up with this table:

1111718749,411543,521839,9879,239,857
